PATENT l hlUEt CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 395,616, dated January 1, 1889. Application filed November 5, 1887. Serial No. 254,430- (No model.)

To aZZ whom it may concern:

Be it known that I, HUGH J I) ruins, of Berkeley, county of Alameda, and State of California, have in vented. an Improvement in Carburetors; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to that class of carburetors in which air is forced into contact with volatile liquid hydrocarbons or oils, whereby it becomes saturated with inflammable vapor and may be conducted through pipes to burners.

My invention consists in a rotary frame mounted within a casing containing the liquid hydrocarbon or oil, said frame carrying an absorbent materialsuch as strips of lampwickwhich by the rotation of the frame are successively immersed in the body of oil and withdrawn saturated to give forth to the air in said chamber their inflammable vapors.

My invention also consists, in combination with the cylindrical oil casing or reservoir in which the air is carbureted, of a superposed feed-casing communicating along the center of its base with the oil-casing, and having the edges of its sides depressed to form receptacles for the oil.

My invention. also consists in the novel combination and arrangement of the air-pump, the oil-casin g with rotary wick-frame, the feedchamber, the aerometer or regulator, and connections, all of which, together with details of construction, I shall hereinafter fully describe.

The object of my invention to provide a simple and effective machine, and one which is compact in its general construction.

Referring to the accompanying drawings, Figure 1 is a perspective view of my carburetor. Fig. 2 is alongitudinal vertical section of same. Fig. 3 is a transverse vertical section. Fig. l is a partial detail of frame D.

A is the box or casing of the air-pump, the cylinder of which is designated by B, said cylinder being rotated by means of a shaft, b, at one end, which carries a drum, 1), to which a cord, 12 is attached, said cord passing over and carrying suitable pulleys, b and having an operating-weight, b". This weight, acting through the cord, causes the rotation of the drum, which, through its shaft Z), effects the rotation of the cylinder of the air-pump, and said weight when run down may be wound up by the application of a key to the square end If of the drum-shaft.

On top of the casing A is firmly secured the cylindrical shell or casing O, which forms the oil-chamber. In this shell is -mounted, by

means of a central shaft, (1, a frame, D, which consists of radial end arms, d, and between which are stretched the horizontal wires (1 of the periphery, said wires being simply hooked into sockets in said arms, whereby they may readily be removed when necessary. Secured to these wires d are pieces of suitable absorbent material, E, preferably lamp-wicks. Handholes F are made in the ends of the cylindrical casing, whereby the wires d may be reached to remove them and the wicks E, which they carry, for the purpose of cleaning said wicks or substituting others.

A rotary motion is imparted to the frame D by means of a sprocket-pulley, d on the end of its shaft (7, from which said pulley an endless chain, (1", extends downwardly to a sprocket-pulley, b, on the drum-shaft Z). 011 top of the cylindrical shell or casing C is fixed the feed-casing l, said casing conforming at its base to the convexity or curvature of the shell 0 for a certain distance, so that on each side of the top of the shell the casing G extends downwardly, forming the depressed portions g, Fig. 3. The casing G communicates with the interior of the cylindrical shell or casing 0 through apertures g, made in the top of said shell and approximately along its center. In the top of the casing G is let the oil-feed pipe H, which is controlled by a suitable cock, and has its lower end just above a deflecting-plate, I, located within the casing G and secured therein in any suitable manner, said deflecting-plate lying in the vertical plane above the apertures g, and having its ends directed toward the depressed portions g of said casing. In the top of said casing is also let the outlet-pipe J, from which the burner-connecting pipe j extends. A hand-hole,

K, is also made in the top of the casing G for the purpose of affording access to its interior. Supported above the casing G, near one end, is an aerometer or airregu1ator, L, which consists of the usual outer shell, 1, containing the water, and the inverted vertically-movable inner cup, Z.

M is a pipe which extends into the hollow center of cylinder B of the air-pump, and, passing out through one end thereof, forms one of the journals of said cylinder, and is connected with a pipe, on, which extends upwardly into the cup Z of the aerometer. A drip-pipe, in,

IO extends downwardly from the pipe m. I

N is a pipe which extends downwardly f ron the cup l of the aerometer into the cylindrical casing C and terminates at a point a little below its central horizontal plane.

The casing A of the ai r- ;u'1m1 contains water up to about the level indicated by the line a: 06, Figs. 2 and 3. The cylindrical shell or casing 0 contains oil to about the level of the liuey y, Figs. 2 and 3. The casing G is packed with an absorbent material-such as rotten wood or charcoal or other suitable substan cesaid packing being here represented by the letter O. The outer vessel, 7, of the aerometer contains, as usual, water.

The operation of the machine is as follows: The rotation. of the cylinder B of the airpump forces the air through the pipe M and pipe m up into the aerometer, from which it is forced downwardly with constant pressure 0 through the pipe N into the cylindrical shell or easing O of the oil-chamber, where it comes in contact with the oil, which is thereby agitated to an extent and carburets the air. The liquid hydrocarbonsuch as gasoline or other 3 5 volatile oil-is fed through the pipe H into the casing G, in which, falling upon the deflectin g-plate I, it is thereby directed, primarily, to the depressed sides 9 of said casing, which act as reservoirs for a considerable quantity. As these reservoirs fill and the packing O of the casing G becomes saturated with the oil, itflowsover and drips down through the apertures g into the casin or shell in which it lies on about thelevel of the line i] 1 as h cretofore stated. The motion of the cylinder of the air-pump commui'iicates rotation through the endless chain. (1 and sprocket-pulleys, heretofore described, to the frame D in the shell 0, so that the wicks E of said frame are brought around successively and immersed in the oil held in said shell; and as said wicks rise from the oil thoroughly saturated therewith, they present an extended surface capable of giving off rapid evaporation, and they thus give to the air their inflammable vapors,

whereby said air, risin from contact with the oil-body partially.carbureted, is completely carbureted, and, passing up through the apertures g and through the absorbent material O in the casing G, is relieved of any excess of hydrocarbon vapor, and, finally, is discharged through the pipe I into the burnerconnections.

There is nothing novel. in the construction of the air-pump cylinder, and I need, therefore, describe it no more particularly than to refer to Fig. 3, in which the cylinder is shown as consisting of three sections separated from each other to leave spaces or apertures b for the air to enter and find its way to the hollow center 11 of the cylinder, in which the end of the discharge-pipe M lies. The cylinder rotating, as each aperture passes below the water, a seal is formed, so that the air in the section is forced into the center of the cylinder, and thence through the pipe-connections into the aerometer. One point of novelty, however, consists in the mounting of this cylinder in such a way as to avoid a central shaft, Fig. 2. This I do by having the inner end of the shaft 1) squared off to enter a square socket in the end plate of the cylinder, the shoulder formed by the squared shaft pro\ 'iding a stop for preventing the cylinder from moving in that direction; The pipe M serves as a journal for the other end of the cylinder, said pipe having screwed upon its external end a coupling, in which serves as a shoulder to prevent the cylinder from moving in that direction, and to this coupling is connected a nipple and pipe-connections m to the pipe m.

P is a gage-glass for denoting the level of oil in the oil-chamber, Fig. 2.

By connecting the cylinder of the air-pump with the wick-carrying frame of the carbureting-chamber I make their operation independent, whereby, when the capacity of the pump is increased, the operation of the wickframe is also increased and the increased volume of air is provided for. The aerometer regulates the supply of air, and when weighted requires an increase in the weight-power for operating the pump-cylinder.

The whole machine, it will. be observed, is compact in construction and is available for operation in any situation.

The depressions g in the feed-casing hold enough oil to keep the absorbent material thoroughly saturated.

Having thus described my invention, what I claim as new, and desire to secure by Iietters Patent, is

1. In a carlniretor, the combination of the cylindrical casing for containing the oil, the frame consisting of radial end arms and horizontal removablysecured wires, the wicks within the casing and suspended from said wires, power mechanism to rotate the frame, the air-pump, and the intervening aerometer or regulator connected with oil-casing,the feedcasing for oil, containing absorbent material.
